# 클래스카드 vs BIGBOX

The clearest difference is in-app purchases: 클래스카드 at none against BIGBOX's 10. 클래스카드 also leads on update cadence (every 4 days vs every 2 weeks) and ratings volume (208 vs 21). BIGBOX's advantage is review sentiment (82% vs 67%). On price, rating, ads and device support there is nothing between them.

Both are free to download. BIGBOX sells 10 one-off in-app purchases. 클래스카드 asks for nothing beyond the download.

클래스카드 holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: 클래스카드 has 208 ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 67% of 클래스카드's written reviews are positive against 82% of BIGBOX's, so the app with the better star average is not the one people write more warmly about.

클래스카드 ships an update every 4 days, BIGBOX every 2 weeks. The most recent releases landed on October 26, 2026 and October 23, 2026 respectively.
